Akumulator tłokowy z zaciskaną nasadką — seria ACP (Europa)
Akumulatory tłokowe ACP mają opatentowaną konstrukcję z zaciskami, która zapewnia wysoką wytrzymałość połączenia nasadek ze stalowymi rurkami oraz doskonałą trwałość zmęczeniową. Rurka ze stali węglowej wysokiej klasy oraz materiał nasadki umożliwiają efektywne odprowadzanie ciepła i są dogładzane oscylacyjnie w celu wydłużenia żywotności uszczelnienia. Seria ACP stanowi dobrą alternatywę dla akumulatorów membranowych, ponieważ może zapewnić większą retencję azotu gazowego oraz ma zwartą i lekką konstrukcję.
Chociaż oferowane akumulatory mają standardową wydajność, konstrukcja obudowy ze stali nierdzewnej umożliwia łatwe wykonanie „niestandardowych" akumulatorów spełniających dokładne wymagania dotyczące wydajności na potrzeby dowolnego zastosowania u klienta.
Akumulatory tłokowe ACP są dostępne w dwóch wersjach: przeznaczonej do ponownego napełniania lub zabezpieczonej przed manipulacją. Modele z możliwością ponownego ładowania umożliwiają użytkownikowi monitorowanie i regulowanie wstępnego ładowania gazem odpowiednio do różnych warunków pracy. Wersje ACP zabezpieczone przed manipulacją i uszczelnione na cały okres eksploatacji są wstępnie ładowane podczas montażu zgodnie ze specyfikacją klienta i całkowicie bezobsługowe.
Firma Parker Olaer opracowała bardzo wyrafinowane oprogramowanie symulacyjne w celu optymalizacji zaleceń przy doborze wielkości akumulatorów hydraulicznych. Oprogramowanie do doboru wielkości akumulatora jest dostępne do pobrania na kacie „Wsparcie produktu".

Gas Bottles
Parker Gas Bottles offer a cost effective solution for customers who would like to have additional gas volume or in situations whereby space limitations prevent the installation of an accumulator with the required accumulator capacity.
Gas bottles are available in carbon and stainless steel and in a wide range of sizes and operating pressures. Gas bottles are also available with one or two ports.
Additional Gas Supply
A gas bottle could be used instead of an additional accumulator to provide higher gas volume thus saving costs. This is especially cost efficient when a high accumulator volume is required for a hydraulic system, a standard carbon steel gas bottle could be used as the gas bottle is not connected directly to the system. Thus creating a significant cost saving.
Space Restrictions
Where space does not permit the installation of the required capacity accumulator, a smaller accumulator may be used by connecting it to a gas bottle(s), which can be located where space is available.
Our standard range of gas bottle is available from 1.6 to 500 Litres and up to 412 bar however a wider range is available upon request (Forged carbon steel type up to 760 bar and Machined type up to 3000 bar).
Benefits
• Cost effective solution for additional gas supply

Why Use Transfer Barrier Accumulators?
Separation of two fluids:
A Transfer Barrier Accumulator can also be used to separate two liquids or a gas and liquid. It is usually a question of separating two liquids, one of which is aggressive or contaminated. To limit the number of parts in contact with the aggressive liquid, it is common practice to put the aggressive fluid inside the bladder and therefore connect on what is normally the gas side. Pending of the accumulator volume, the displaced volume must not exceed 80% of the volume of the transfer accumulator.
Undersea pressure compensation:
Many subsea drilling and production applications demand resistance to seawater and applications can utilize transfer barriers in undersea pressure compensation application…allowing ocean water into fluid port to apply head pressure to internally stored hydraulic oil. Pressurized fluid is then discharged to application for actuation.
Used in Series with Gas Bottles:
This product range is a special adaptation of the bladder accumulator, with a pipe connected to the gas side of the accumulator. The most common application is to use the transfer accumulator in energy storage applications. The accumulator is connected to an additional volume of nitrogen, for example a gas cylinder. This increases the total volume of the system. Such systems are often mounted together in a battery or rack type installation.

Components of a Transfer Barrier Type Accumulator:
Shell:
Transfer Barrier shells are made from chrome-molybdenum alloy steel (SA372) with forged ends. All sizes comply with ASME/PED material and design specifications. Two and a half gallon and larger accumulators are supplied with ASME and PED certifications as standard. Stainless steel and exotic metal shells are available upon request.
Bladder:
Polymer bladders are manufactured in-house to control the material blending, molding, critical seam assembly, and curing processes. It is widely accepted that Parker’s “Made in the USA” bladder designs are the highest quality bladders in the industry. Bladders are offered in five different standard compounds to suit a wide variety of fluids and operating temperatures. Special compounds are available for extreme, unusual or severe applications.
Bladder Stems:
All bladder accumulators, sizes 2.5 gallon and larger, are fitted as standard with integrated, one-piece bladder stems for ease of serviceability.
Port Assemblies:
Standard oil service ports are made from high-strength alloy steel for maximum durability. Chemical and water service port assemblies are made from electroless nickel plated or stainless steel materials for maximum corrosion resistance.
Fluid Ports:
SAE straight thread, NPTF, SAE Code 61 and SAE Code 62 4-bolt split flange, and High-flow ports are available. Bleed ports are included as standard on sizes 2.5 gallon and larger; not available on flange ports.
Types of Transfer Barrier Accumulators:
Bottom Repairable design, due to its simplicity and cost effectiveness, has become the de facto “Industry Standard” of transfer barrier accumulator. For systems requiring a fast discharge or “dumping” rate, the High-flow accumulator incorporates a large port assembly capable of flows up to 600 GPM (2270 LPM). Sizes range from 2-1/2 to 15 gallons.
Fluid Connection Port:
Transfer Barriers have an inlet port for each type of fluid. Whether you are using the transfer barrier accumulator for two fluids or a liquid/gas separation…the high flow port attached to the bladder itself needs to be compatible with fluid and temperature specifications. This port is available in many different material options, like nickel plated steel or stainless steel, and is molded directly onto the bladder at factory.
Standard and Optional Bladders:
A variety of bladders are offered to suit a wide range of fluids and operating temperatures. The following table lists the optional bladders available, their recommended operating temperature ranges, and the types of fluids that are generally compatible.
Bladder Compounds:

Certifications for Global Requirements
Certifications for accumulators vary – often quite significantly – depending upon the application or industry in which will be used and/or the country they will be used in. Sorting through and understanding the myriad of requirements that may be encountered is a daunting and difficult task. A truly global certification standard, meanwhile, remained all but impossible to achieve due to the parameters that must be met for individual country regulations.
Parker’s Accumulator & Cooler Division engineers have extensively researched and fully understand these pressure vessel codes. From the United States to Europe, Asia and Australia, our experts are ready and able to help you avoid the many costly and time consuming pitfalls you didn’t see coming. Furthermore, ACD can provide the global accumulator certifications you need.
Parker ACD now offers global certified ASME/CE/AS1210/CRN transfer barrier accumulators, one rationalized design which meshes the very best of the Greer, Parker and Olaer brands. As the global leader in motion control, Parker appreciates that our customers demand one product that is available and acceptable worldwide. No matter where you need to be, Parker’s Accumulator & Cooler Division will be there to support you with the necessary products, services and global certifications.
Accumulators, transfer barriers and gas bottles are pressure vessels that are subject to safety laws, regulations, and ordinances that are valid in the state or country of installation. Other particular regulations must be observed in certain industries such as mining, shipbuilding and aircraft. This brief will discuss the two fundamental design codes and several of the most common certifications. Since many more certifications exist, we recommend contacting Parker’s Accumulator & Cooler Division engineers to ensure proper conformance to those standards.
Two Base Design Codes
While many countries and manufacturers have their own regulations and quality standards for hydraulic accumulators, gas bottles and transfer barriers; most refer back to one of two base design codes. The oldest and most referenced design code for pressure vessels is ASME. Originally written to create a standard for the manufacture of boilers on steam locomotives, the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII, Division 1 has evolved into requirements for unfired pressure vessels and accumulators in the United States. This section requires the following:
1. Certification on vessels with internal diameters of 6" or greater.
2. Certified vessels carry the “U” symbol on them as evidence that they were designed and manufactured in accordance with the Code. The “U” symbol is an internationally recognized symbol of design and manufacturing quality.
3. Accumulators must be manufactured from materials that meet ASME specifications for traceability.
4. A design factor of 4:1 in the ratio of minimum burst pressure to rated pressure. All design factors are with respect to the specified minimum tensile strength of the material.
5. ASME requires that each vessel be marked with the design pressure at the Minimum Design Metal
Temperature (MDMT) for the vessel.
6. Surveillance of an approved quality system, like ISO 9001.
7. All hydrostatic testing to be witnessed by a recognized authorized inspection agency. The 4:1 design factor requirement is mandatory for all accumulators with ASME Certification with the exception of those that comply with a specific rule within the Code called “Appendix 22.” Appendix 22 permits that accumulators manufactured with “forged” shells and with openings of a specified maximum size may be certified with a design factor of 3:1 in the ratio of burst pressure to rated pressure. This includes fluid separator style accumulators.
The second base design code is the European Pressure Equipment Directive. In May 2002, the Directive
97/23/EC (Pressure Equipment Directive) came into regulation in the European Union. This directive applies to the design, manufacture, testing and conformity assessment of pressure equipment and assemblies of pressure equipment that operate over 0.5 bar. The directive requires the following:
1. The operating fluids must be in Group 2 (non-hazardous).
2. Certified vessels with a gas capacity volume of 2.5 G or greater must be CE marked
3. Certified vessels must be manufactured from materials that meet PED specifications for traceability.
4. Certified product must pass a low temperature Charpy test (temperature to be determined by application or customer).
5. Surveillance of an approved quality system, such as ISO 9001.
6. All hydrostatic testing to be witnessed by an approved notified body. Parker holds module H1 certification – allowing us to self-certify accumulators saving our customers time and money.
7. Once installed, equipment and accumulator inspection as well as operational safety are controlled by national laws.
Country Certifications
Below is a brief list of the most popular country standards that Parker ACD can provide:
1. Canada: Canadian Registration Numbers (CRN) can be obtained by constructing an accumulator from ASME-certified material using ASME standards of design then applying for the registration number. Each province has its own registration number, thus the end destination of the accumulator must be known. Some provinces are allowing alternative design codes like the PED for specific markets such as farming and mining. Contact Parker ACD for detailed specifics.
2. Australia: AS1210 is a standard based on ASME design requirements. Additional hydrostatic testing is required. The accumulator must be tested at 1.5 times the design pressure for 30 minutes plus an additional 1 minute per mm of thickness of the shell/vessel.
3. China: Accumulators shipped to China often require Special Equipment Licensing Office (SELO) approval. China currently accepts both PED and ASME design standards. To manufacture accumulators for the Chinese marketplace, a manufacturing license is required. Paperwork both before and after the purchase of the accumulator is required for submittal to China for tracking purposes.
4. Russia: Accumulators shipped to Russia often require CUTR or the expired GOST approval. CUTR currently accepts both PED and ASME design standards. A technical file called a “passport” must be submitted with each accumulator shipment.
5. Brazil: The Regulatory Rule NR-13 establishes the minimum conditions for the installation, operation, maintenance and inspection of pressure vessels and boilers in Brazil. Both ASME and the PED are acceptable design codes, but ASME designs are more prevalent. When NR-13 is required, Parker’s engineers can submit a technical file to Brazilian Registered Engineers (BRE) for approval. After approval, an inspection at the place of installation will be performed by the BRE. This could also include hydrostatic testing.

Bladder Stems:
All bladder accumulators, sizes 1 gallon and larger, are fitted as standard with two-piece bladder stems with replaceable gas valve cartridge for ease of serviceability. Also, the two piece stem will accept high-flow poppet type gas valves and permanent mount gauge adapters.
Port Assemblies:
Standard oil service ports are made from high-strength alloy steel for maximum durability. Chemical and water service port assemblies are made from electroless nickel plated or stainless steel materials for maximum corrosion resistance.
Fluid Ports:
SAE straight thread, NPTF, SAE Code 61 and SAE Code 62 4-bolt split flange, and High-flow ports are available. Bleed ports are included as standard on sizes 1 gallon and larger; not available on flange ports.
Gas Valve:
All accumulators are fitted with a gas valve for ease of gas pre-charging. One-gallon and larger 3000 PSI units are equipped with a cored gas valve cartridge (ISO-4570-8V1) for ease of maintenance. 5000 PSI units are equipped with a high pressure cored gas valve cartridge with an option of a high-flow poppet gas valve cartridge (L07689000K). For safety, the gas valve vents if unscrewed.
Types of Bladder Accumulators:
Bottom Repairable design, due to its simplicity and cost effectiveness, has become the de facto “Industry Standard” bladder accumulator. Sizes range from 10 cu in to 15 gallons.
The Top Repairable Accumulator permits easy checking and maintenance of the bladder without removing the accumulator from the service line, saving time and money. Sizes range from 2.5 G to 15 G.
For systems requiring a fast discharge or “dumping” rate, the High-flow accumulator incorporates a large port assembly capable of flows up to 600 GPM (2270 LPM). Sizes range from 2-1/2 to 15 gallons.

Certifications for Global Requirements
Certifications for accumulators vary – often quite significantly – depending upon the application or industry in which will be used and/or the country they will be used in. Sorting through and understanding the myriad of requirements that may be encountered is a daunting and difficult task. A truly global certification standard, meanwhile, remained all but impossible to achieve due to the parameters that must be met for individual country regulations.
Parker’s Accumulator & Cooler Division engineers have extensively researched and fully understand these pressure vessel codes. From the United States to Europe, Asia and Australia, our experts are ready and able to help you avoid the many costly and time consuming pitfalls you didn’t see coming. Furthermore, ACD can provide the global accumulator certifications you need.
Parker ACD now offers global certified ASME/CE/CRN/AS1210 bladder accumulators as standard on 1 gallon and larger sizes. As the global leader in motion control, Parker appreciates that our customers demand one product that is available and acceptable worldwide. No matter where you need to be, Parker’s Accumulator & Cooler Division will be there to support you with the necessary products, services and global certifications.
Accumulators and gas bottles are pressure vessels that are subject to safety laws, regulations, and ordinances that are valid in the state or country of installation. Other particular regulations must be observed in certain industries such as mining, shipbuilding and aircraft. This brief will discuss the two fundamental design codes and several of the most common certifications. Since many more certifications exist, we recommend contacting Parker’s Accumulator & Cooler Division engineers to ensure proper conformance to those standards.
Two Base Design Codes
While many countries and manufacturers have their own regulations and quality standards for hydraulic accumulators, most refer back to one of two base design codes. The oldest and most referenced design code for pressure vessels is ASME. Originally written to create a standard for the manufacture of boilers on steam locomotives, the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII, Division 1 has evolved into requirements for unfired pressure vessels and accumulators in the United States. This section requires the following:
1. Certification on vessels with internal diameters of 6" or greater.
2. Certified vessels carry the “U” symbol on them as evidence that they were designed and manufactured in accordance with the Code. The “U” symbol is an internationally recognized symbol of design and manufacturing quality.
3. Accumulators must be manufactured from materials that meet ASME specifications for traceability.
4. A design factor of 3.5:1 in the ratio of minimum burst pressure to rated pressure. All design factors are with respect to the specified minimum tensile strength of the material. 3.5:1 is specific for a seamless shell design as those used for the bladder accumulators.
5. ASME requires that each vessel be marked with the design pressure at the Minimum Design Metal
Temperature (MDMT) for the vessel.
6. Surveillance of an approved quality system, like ISO 9001.
7. All hydrostatic testing to be witnessed by a recognized authorized inspection agency. The 3.5:1 design factor requirement is mandatory for all accumulators with ASME Certification with the exception of those that comply with a specific rule within the Code called “Appendix 22.” Appendix 22 permits that accumulators manufactured with “forged” shells and with openings of a specified maximum size may be certified with a design factor of 3:1 in the ratio of burst pressure to rated pressure. This includes bladder style accumulators.
The second base design code is the European Pressure Equipment Directive. In May 2002, the Directive
97/23/EC (Pressure Equipment Directive) came into regulation in the European Union. This directive applies to the design, manufacture, testing and conformity assessment of pressure equipment and assemblies of pressure equipment that operate over 0.5 bar. The directive requires the following:
1. The operating fluids must be in Group 2 (non-hazardous).
2. Certified vessels with a volume greater than 1 liter gas capacity must be CE marked.
3. Certified vessels must be manufactured from materials that meet PED specifications for traceability.
4. Certified product must pass a low temperature Charpy test (temperature to be determined by application or customer).
5. Surveillance of an approved quality system, such as ISO 9001.
6. All hydrostatic testing to be witnessed by an approved notified body. Parker holds module H1 certification – allowing us to self-certify accumulators saving our customers time and money.
7. Once installed, equipment and accumulator inspection as well as operational safety are controlled by national laws.
Accumulators with a volume less than 1 liter, of gas capacity, fall within the guidelines of Sound Engineering Practice (SEP). Accumulators built to SEP must be built to a known standard and have an approved notified body approve the design and the technical file. These accumulators do not carry a CE marking.
Country Certifications
Below is a brief list of the most popular country standards that Parker ACD can provide:
1. Canada: Canadian Registration Numbers (CRN) can be obtained by constructing an accumulator from ASME-certified material using ASME standards of design then applying for the registration number. Each province has its own registration number, thus the end destination of the accumulator must be known. Some provinces are allowing alternative design codes like the PED for specific markets such as farming and mining. CRN is standard on 1gallon and larger bladder accumulators. Contact Parker ACD for detailed specifics.
2. Australia: AS1210 is a standard based on ASME design requirements. Additional hydrostatic testing is required. The accumulator must be tested at 1.5 times the design pressure for 30 minutes plus an additional 1 minute per mm of thickness of the shell/vessel. AS1210 is standard on 1gallon and larger bladder accumulators.
3. China: Accumulators shipped to China often require Special Equipment Licensing Office (SELO) approval. China currently accepts both PED and ASME design standards. To manufacture accumulators for the Chinese marketplace, a manufacturing license is required. Paperwork both before and after the purchase of the accumulator is required for submittal to China for tracking purposes.
4. Russia: Accumulators shipped to Russia often require CUTR approval. CUTR currently accepts both PED and ASME design standards. A technical file called a “passport” must be submitted with each accumulator shipment.
5. Brazil: The Regulatory Rule NR-13 establishes the minimum conditions for the installation, operation, maintenance and inspection of pressure vessels and boilers in Brazil. Both ASME and the PED are acceptable design codes, but ASME designs are more prevalent. When NR-13 is required, Parker’s engineers can submit a technical file to Brazilian Registered Engineers (BRE) for approval. After approval, an inspection at the place of installation will be performed by the BRE. This could also include hydrostatic testing.
Industry/Market Standards
1. American Bureau of Shipping (ABS): Is required for accumulators installed on shipping vessels and oil rigs. To be added to a Product Design Assessment Certificate, accumulators must meet ASME design requirements plus any additional ABS requirements. Parker has an ABS Certificate of Manufacturing Assessment and many accumulators are listed on the Bureau’s List of Type Approved Products. All ABS approved accumulators must be witness tested at Parker by an ABS inspector.
2. Det Norske Veritas (DNV): Off-shore Standard DNVOS-E101 is often required for accumulators on off-shore oil and gas applications, particularly in the North Sea. Many of Parker’s accumulators have DNV Type Approval.
Parker ACD is proud to offer dual-certified ASME/CE bladder accumulators (along with CRN/AS1210), a design which meshes the very best of the Greer and Olaer brands. As the global leader in motion control, Parker appreciates that our customers demand one product that is available and acceptable worldwide.

High Pressure Piston Accumulator with Crimped Design- HCP Series
The high pressure piston accumulator (HCP) incorporate a patented crimped design that provides high-strength coupling of caps to steel tube plus superior fatigue life. High grade carbon steel tube and end cap material allows heat to dissipate effectively and is micro-finished for extended seal life.
Parker’s high pressure crimped piston accumulators (HCP series) are an ideal replacement for applications whereby membrane (also known as diaphragm) accumulators are utilized. One piston accumulator can deliver the same performance as five or more membrane accumulators. Reducing the number of required accumulators from five or more to just one piston accumulator will reduce components such as hoses and connectors and will;
* Reduce potential leak points
* Generate additional space
* Minimise installation time
* Reduce maintenance.
Although these accumulators are offered in standard capacities, the steel shell design affords an easy way to "custom" manufacture an accumulator to meet the exact capacity for any customer application.
Parker have developed very sophisticated simulation software to optimize sizing recommendations for hydraulic accumulators. You can download the accumulator sizing software from the Product Support tab.
